Description
| - Pomocí UV-VIS spektroskopie byl sledován fotorozpad organokovových komplexů. Byly získány spektra 2x10-4 M roztoku iniciátorů v acetonitrilu a sledován úbytek pásu 245 nm po ozáření vysokotlakou rtuťovou výbojkou. Byly stanoveny extinkční koeficienty a energie nutné k dosažení 50% konverze. Účinnost polymerace byla sledována FTIR spektroskopií ve vinyletherovém a epoxidovém monomeru. (cs)
- Several arene-iron complexes ((5-2,4-cyclopentadien-1-yl)[(1,2,3,4,5,6-)-arene] ferrous hexafluorophosphate) were tested as photoinitiators for cationic polymerization. The UV light decomposes arene-ironcyclopentadienyl (arene-Fe+Cp) cation selectively to the corresponding aromatic compound and iron cyclopentadiene (CpFe+) cation. Structure of aromatic compound affects decomposition upon UV light. FeCp+ formed during irradiation is active species for cationic polymerization. Decomposition of arene-iron initiators upon UV light was followed by UV-VIS spectroscopy. It was measured the decrease of absorption band at about 245 nm after irradiation 2x10-4 M solution in acetonitrile. Super pressure mercury lamp was used as source of UV radiation. Extinction coefficients and energies need for achieving 50% conversion were calculated for all initiators. Efficiency of polymerization initiatiation was followed by FTIR spectroscopy in vinylether and epoxide monomers. Results from FTIR showed that most of pre
